Standalone DZ-11 driver Hi all, I'm working on a new version of my Vtserver, which allows a PDP-11 with no tape drive to boot from a Unix/Linux server (via serial cable) and install a UNIX. See ftp://minnie.cs.adfa.edu.au/pub/PDP-11/Vtserver At present I'm working on a new version which uses the 2.11BSD boot code so as to support more disk drives. The work in progress is at: http://minnie.cs.adfa.edu.au/Vtserver. At present it's not usable unless you have a PDP-11/45. I've got a potential user with an 11/34, two RK05s and a DZ-11. I can't find any details of DZ-11 here in my peripherals handbooks, and the 2.11 kernel drivers are a bit too complicated to read. My existing KL-11 driver is below. Can someone come up with a standalone equivalent for a DZ-11, or point me at some docs? I'll be away from 1st to 14th Feb, so there may be some delays in responding.

I've also tried the "Dennis" images, which are supposedly straight RK05 images; E11 won't boot 'em. One issue on which I'm not clear: where is the boot address? Stuff at loc 0 doesn't look like boot instructions. If I could get an image to run in an emulator (as I mentioned, I'm running E11 from DBit), I'd write some cheesy little loader to bring it down the serial line (I already have it sketched out); but until I can at least get one to boot in the emulator, I'm reluctant to spend the hours (at 9600 baud) to spray it onto a disk. <sigh> Any suggestions you may have would be greatly appreciated. -- Ian -----Original Message----- From: Ken Wellsch [mailto:kwellsch@tampabay.rr.com] Sent: Tuesday, January 30, 2001 10:30 AM To: Carl Lowenstein Cc: pups(a)minnie.cs.adfa.edu.au Subject: Re: [pups] A bootable disk image for a PDP-11/34?

I've tar/gzip'ed the bundle. Do you want me to try and UUencode it and mail it to you? It is nearly 1 Mbyte in binary form... Oh yeah, as Warren mentioned, stock V6 does not run on a '34. I think it ran on a '40. I know it can run on a '34 because in 1980 I started using UNIX, V6 running on a '34 B^) Cheers, -- Ken Ian King wrote: at baud) Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id AAA29613 for pups-liszt; Thu, 1 Feb 2001 00:21:49 +1100 (EST) (envelope-from owner-pups(a)minnie.cs.adfa.edu.au) Received: from arundel.fortyfour.org (138bus2.tampabay.rr.com [24.94.138.2]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id AAA29604 for &lt;pups(a)minnie.cs.adfa.edu.au&gt;; Thu, 1 Feb 2001 00:21:43 +1100 (EST) (envelope-from kwellsch(a)tampabay.rr.com) Received: from tampabay.rr.com (localhost [127.0.0.1]) by arundel.fortyfour.org (8.11.0/8.11.0) with ESMTP id f0VDK7R00577 for &lt;pups(a)minnie.cs.adfa.edu.au&gt;; Wed, 31 Jan 2001 08:20:07 -0500 (EST) Message-ID: &lt;3A781106.F7302A5A(a)tampabay.rr.com&gt; Date: Wed, 31 Jan 2001 08:20:06 -0500 From: Ken Wellsch &lt;kwellsch(a)tampabay.rr.com&gt; X-Mailer: Mozilla 4.76 [en] (X11; U; NetBSD 1.5.1_ALPHA i386) X-Accept-Language: en MIME-Version: 1.0 To: pups(a)minnie.cs.adfa.edu.au Subject: Re: [pups] A bootable disk image for a PDP-11/34?

The date setting format on V6 appears to be '1231245999', that is two digits for: month, day, hour, minute, year. A trailing 'p' means the hours are 12 based (and it is PM), otherwise 24 based. I can confirm as I expected that setting 0131110301 puts me at 1970 B^) No big deal. I can see in the 'date' source what it is doing... Thanks for the 'put it into the year 2001' method! -- Ken
